Web72 rows · In general, an index of refraction is a complex numberwith both a real and … WebMar 4, 2024 · Snell's law, or the law of refraction, describes the relationship between the angles of incidence θ₁ and refraction θ₂ and the refractive indices ( n ₁, n ₂) of two media: n ₁sin (θ₁) = n ₂sin (θ₂). The law of refraction allows us to predict the amount of bend when light travels from one medium to another. Does Snell's law apply to all waves?

When the incident angle equals the critical angle ( θ 1 = θ c ), the angle of refraction is 90° ( θ 2 = 90°). Noting that sin 90° = 1, Snell’s law in this case becomes. n 1 sin θ 1 = n 2. The critical angle, θ c, for a given combination of materials is thus.
